Stars, including the Sun, produce light energy through nuclear fusion reactions, while Earth reflects and absorbs sunlight without producing light energy.
The main differences between a star, the Sun, and Earth lie in their production of light energy. Stars, including the Sun, produce light energy through nuclear fusion reactions at their cores. In contrast, Earth does not produce light energy but rather reflects and absorbs sunlight from the Sun. While the Sun is a star that emits light energy, Earth is a planet that orbits the Sun and benefits from the light it emits.
